The Government of Jersey has launched an interactive Rooftop Solar Panel Suitability Map,
enabling Islanders to check whether their property may be suitable for solar panels.
Originally developed as an internal resource to assess the photovoltaic, PV, potential of States-owned properties, the map was created by Jersey Property Holdings under the remit of the
Minister for Infrastructure. It is now being made available to the public as an information tool to
raise awareness and help Islanders consider whether investing in solar PV could be a viable
option.
Infrastructure & Environment is working with Jersey Electricity to explore opportunities for
Islanders to generate their own renewable energy. While the Government is also close to
agreeing a Framework Agreement for solar PV installations on Government-owned properties,
which will help accelerate the adoption of renewable energy across the public estate.
Mapping solar suitability
The map uses the Government’s 3D Digital Surface Model, which captures ground
elevation and the shape and height of buildings, trees, and other features. By simulating the
sun’s movement throughout the year, the model estimates annual solar radiation for each
rooftop, accounting for shading from nearby objects.
Understanding the map
- High exposure areas indicate rooftops that are more suitable for solar panels
- Shaded or obstructed areas may be less viable
- The map is intended as a starting point, not a substitute for professional on-site
assessments
Certain properties were excluded from the map, including: Listed buildings, which are unlikely
to receive planning permission for solar panels and Polytunnels and glasshouses, due to
structural limitations.

Ralph Buchholz, Head of Corporate Property Strategy at the Government of Jersey,
explained:
“Using advanced 3D modelling, we’ve been able to analyse rooftops across the Island to
determine which buildings are most suitable for solar PV installations."
